摘要：
A light-emitting material containing a compound represented by the general formula (1) is capable of achieving an excellent external quantum efficiency on using in an organic light-emitting device. R1 to R8 represent a hydrogen atom or a substituent, provided that at least one of R1 to R8 represents a substituted or unsubstituted carbazolyl group; and Ar1 to Ar3 represent a substituted or unsubstituted aromatic ring or heteroaromatic ring.
